Three people were killed in a collision Tuesday morning that involved two semi-trucks and one car. All three adult victims were in the car.
It happened at around 10:30 a.m. on Highway 55 east of Grassland, Alta., between Township Road 674 and Range Road 190.
RCMP said preliminary investigation indicates a car heading south was trying to pass a vehicle on the highway when it collided with a semi-tractor heading north. Then, a separate crash happened with a southbound semi.
The three adults in the car were from Fort McMurray. They were pronounced dead at the scene, RCMP said. Another passenger in the car and the driver of the northbound semi were taken to hospital and then flown to Edmonton with serious, life-threatening injuries. The driver of the southbound semi suffered minor injuries, RCMP said.
RCMP said speed and weather conditions are believed to have been factors. Heavy blowing snow, low visibility and icy conditions were reported on the highway.
No charges are expected. The victims have not been identified by RCMP.
RCMP said that as of 11:15 a.m. Wednesday, traffic was still being diverted around the crash scene on Highway 55. Delays were expected for another two hours.
The scene of the crash is roughly 200 kilometres northeast of Edmonton.
